Odoo ERP for Professional Services Firms

Common Problems for Professional Services Firms

O2B Technologies implements Odoo ERP for US firms that bill for time and expertise: law firms, accounting and tax firms, engineering and architecture firms, and marketing and creative agencies. Odoo captures every billable hour, bills it correctly, and shows it in your profit reports.

How Odoo Solves Them

US professional services firms bill for time and expertise, and their operations run on clients, matters or projects, people and fees. When timesheets, projects and billing live in different tools, hours are missed, invoices go out late, and nobody can say which client or matter is profitable. Odoo replaces those disconnected tools with one connected system for clients, projects, people and finances.

This page is for any expert-services firm that bills for time and knowledge. It is different from our Consulting page, which covers consulting firms only; our IT Services page, which centers on tickets, SLAs and hardware; and our Financial Services page, which covers regulated client firms.

Yes. Odoo bills hourly work from approved timesheets, fixed-fee and milestone work from the project or sales order, and retainers through recurring invoices, with fee rules per client or project.
Yes. Timesheets can be logged from a mobile browser or the Odoo app, including timer entry, so time is captured at the desk or on the move.
Yes. Because hours, cost and revenue are linked to the client, matter or project, Odoo reports profit per client, matter and project instead of one firm-wide number.
In most cases, yes. Odoo covers CRM, projects, timesheets, billing and accounting in one system, and we build the custom fields and workflows a practice management or PSA tool would have provided.
Yes. We migrate customers, open invoices, balances and historical transactions from QuickBooks into Odoo Accounting before go-live, so your firm starts on one system instead of two.
It depends on scope. A single-office firm typically goes live in 6 to 10 weeks, while a multi-office or multi-firm setup with custom billing and integrations takes longer.
